Reviews

Celebrating 80+ years of service in the great state of Michigan

"We appreciate the personal and professional service..."

Today we had our annual maintenance check of our new furnace. Martin P. did a great job explaining everything he was doing and promptly making a few adjustments. We appreciate the personal and professional service, both at our initial installation about a year ago and the follow-ups since then. Many thanks! We'll continue recommending T&G.
